This patch set adds support for reading/writing the Matroska BlockAdditionMapping elements, as well as for reading/writing dvcC/dvvC blocks in Matroska.
Created utility functions to read/write Dolby Vision boxes for ISOM. This was done to avoid duplicating the code, as the Matroska blocks and MOV boxes follow the same specification, defined by Dolby. Refactored the reading/writing in mov/movenc to use the new dovi_isom functions. v10: https://ffmpeg.org/pipermail/ffmpeg-devel/2021-December/289645.html Changes since v10: - dovi_isom: Limited written values to fit into the amount of bits. - matroskaenc: Corrected mkv_write_dovi to only allow profiles that are valid for dvcC/dvvC configurations. - mov: Improved code to be more concise. quietvoid (5): avformat/dovi_isom: Implement Dolby Vision configuration parsing/writing avformat/matroska{dec, enc}: Parse BlockAdditionMapping elements avformat/mov: Refactor mov_read_dvcc_dvvc to use ff_isom_parse_dvcc_dvvc avformat/movenc: Refactor mov_write_dvcc_dvvc_tag to use ff_isom_put_dvcc_dvvc fate/matroska: Add tests for reading/writing BlockAdditionMapping elements libavformat/Makefile | 4 +- libavformat/dovi_isom.c | 118 ++++++++++ libavformat/dovi_isom.h | 35 +++ libavformat/matroska.h | 9 + libavformat/matroskadec.c | 58 ++++- libavformat/matroskaenc.c | 37 +++ libavformat/mov.c | 50 +---- libavformat/movenc.c | 24 +- tests/fate/matroska.mak | 9 + tests/ref/fate/matroska-dovi-config-profile5 | 13 ++ tests/ref/fate/matroska-dovi-write-config | 223 +++++++++++++++++++ 11 files changed, 516 insertions(+), 64 deletions(-) create mode 100644 libavformat/dovi_isom.c create mode 100644 libavformat/dovi_isom.h create mode 100644 tests/ref/fate/matroska-dovi-config-profile5 create mode 100644 tests/ref/fate/matroska-dovi-write-config -- 2.34.1 _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
